I dreamed that I had a quarrel with my friend. It was a terrible quarrel. Then I woke up in a daze. I can't move my hands and feet, like a ghost in bed. What does this mean?

This should be a nightmare. Maybe you are too tired, too nervous or too scared in your dream, so although you are conscious, your muscles haven't woken up yet. If this happens again, I suggest you grind your teeth or roll your eyes first, so that you can exercise your muscles and recover after a while. I often do this.
